The invention relates to the technical field of e-commerce
data management, in particular to a
big data management system based on cross-border e-commerce, which comprises a
data acquisition module, a multi-layer graph construction module, a multi-layer graph
processing module and a multi-layer graph
application module, and is characterized in that the
data acquisition module collects commodity data used by users, including the users, commodities, operation behaviors and user emotions; the multi-layer graph construction module is used for forming a commodity recommendation multi-layer graph and constructing nodes and edges in emotion, behavior and time layer graphs so as to realize fine modeling of a complex relation; the multi-layer graph
processing module calculates embedded vectors of all
layers of graphs, and the embedded vectors are fused into aggregation embedded vectors through a full connection layer; and the multi-layer graph
application module optimizes the training of a
recommendation model by using an aggregation embedded vector, identifies potential interested commodities of the user by predicting a recommendation
list, and particularly improves the relevance and individuation of recommendation in combination with an emotion layer graph weight, so that the problem that a recommendation
system cannot timely and accurately respond to user requirements is solved, and the user experience is improved. And the
user satisfaction and the platform
viscosity are improved.
